- HAND SIGNAL LIGHT.-

Application filed ctober24, 1925. smrnoreeeao.

This invention relates generally to hand operated signal lamp It is theobjectof this invention to provide asignal lamp which may be held ontheoperators hand such as by attachment to one of his fingers, palm, orotherwise, and which may be operated by the movements of the-hand orfingers. specific embodiment of the invention disclosed and describedherein, has special application to'manual signaling by automobileoperators. It will become obvious that the lamp has many otherapplications and uses.

for various signaling and illuminating purposes, such as by ushers intheaters and the like.

The casingof the lamp consists of the body. portion and the cover 11.The body portion 10 which is preferably stamped out of an integral pieceof sheet metal, com prises an oblongportion l2 and a circular portion13, the two portions being connected by a constricted narrow portion 14.The circular portion 13 is provided with slots 15 and 16 on itsperiphery, as shown in Fig. 2. The back face of the body portion 10 isprovided with two sockets 17 and 18 for the reception of the ends of theholding ring 19. The sockets 17 and 18 are preferably integral with thebody of the casing and stamped out from the back of the casing.

The cover 11 is shaped in such a manner as to conform to the shape ofthe body 10 of the casing. The cover 11 is also provided with an oblongportion 20 and a circular portion 22. The circular portion of the coveris provided with a circular opening 23 which may be of any size desiredand which is in the preferred embodiment of the invention, of a diameterthat approximates the diameter of the circular portion 21. V

The body of the casing 10 is provided with a notch 24 which cooperateswith a lug 25 on the cover 11 for the purpose of assembling the twoparts and holding the same in closed position as shown in Figs. 2 and 3.'The lower edge of the cover is pro vided with a teat 26 whichcooperates wlth an aperture 27 in the lower edge of the The In theconstricted portion and 6 show det-ailsof the conbody of the casing.

parts of the casing is accomplished by insertformed to. the shape shown,out of a piece. of

sheet metal. It is providedwith two plates 31 and 32 which aredisposcdin substantially parallel planes andare connected together by means ofthe back plate The plate32 is provided with downwardly extending wings34 and 35 which are shaped to conform with the inner sides of theconstricted por.-.' tion 14 of the body of the casing. The socket 30 isheld in position by the frictional engagement of the wings 34, andagainst th walls of the casing. The plates 31 and 32 are provided witliregistering apertures-39 and which aredesigned to receive the threadedlampbase 36ofthe'lamp 37. The center contact38 of the lamp projectsbeyond the aperture 40 into the oblong portion of the casing.

lVithin the oblong portion of the casing is placed a sn iall'electriccell 41 which is provided with two contact terminals 42 and The contactterminal. 42 is longer than the contact terminal 43 and extends to a 1point in contact with the center contact 38 and is always in contacttherewith. The contact terminal 43 is normally out of con tact with thecasing of the lamp. The resilient switch contact strip 44 is riveted tothe inner face of the circular portion of the body of the casing 10 bymeans of the rivet 45. A knob 46 is attached to the strip 44 andprojects outwardly of the casing through the aperture 47 in the casing.The contact strip 44' passes under the plates 31 and 32 through notches48 and 49 provided therefor, and has a bent port-ion 50 which projectsinto proximity with the terminal strip 43. It will be seen that bydepressing the knob 46 the resilient contact strip 44 is depressed insuch a manner that its free end 50 comes in contact with theterminalstrip bulb 'is completed and the electric bulb is il- I luminated. 'Whenthe pressure on the knob 46 is released, the circuit is broken. 'Atransparent device 50 shaped inthe manner shown in Fig. and madepreferably-of celluloid or other similar material,.is placed in thecircular portio-nof the casing. The

I Y central portion 51 of the faceof the element 50 is painted red forsignaling purposes.

In order to prevent accidental closing of -thehcircuit,. a lockingdevice is provided 'WlllQll under normal conditions and -when I thesignal lamp is not intended for use, will prevent the accidental closingor the -cn'-,

cuit. -The locking device comprises a strip 52 which is pivotallyriveted to the back of the casing at 53. Its free end 55 is de signed tobe inserted into, thespace between theknob 46 and the back ofthe casing10.

The free end 55v is provided with a notch :54

avhich engages the shaft of the knob and the other end of the strip 53which projects beyond the casing to facilitate the operation thereof, isserrated. v I

i'The signal lamp is held on the backt of the operators hand bymountingthe ring :19 on one of the fingers of the operators hand. Normally withthe operators hand on the driverswheel, the hand and fingers are spacedfrom the operating knob 46' and the circuit of the electric bulb isopen.

WVhen, however, the operator. extends his arm for signalling purposes,his hand is straightened and thereby comes in contact with the operatingknob 46 and depresses it, whereby the contact strip 44 is depressed intocontact with the'termi-nal'strip 43 and the signaling device isautomatically illumi nated. The ring 19 serves as a iulcrum or as areaction member for the linger so as to facilitate the application ofpressure to a the operative knob. It is obvious that in place of thering 1 9 which is designed to he slipped over the operators finger, ahandle large enough to slip over the operators palm may be used withoutaltering the operation of the lamp.
